CHARLES H. MCCORMICK, OF BOONTON, NEW JERSEY.

APPARATUS FOR HEATING BOILERS.

Application filed February 27, 1915.

To all whom it may concern:

Be it known that I, CHARLES H. Mo- ConMIoK, a citizen of the United States, residing at Boonton, in the county of Morris and State of New Jersey, have invented certain new and useful Improvements in Apparatus for Heating Boilers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in apparatus for heating boilers and the object in view is to produce a simple and efficient apparatus of this nature so arranged that twoor more boilers may be heated from one furnace by combining steam and air.

The invention comprises various details of construction, combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claim.

I illustrate my invention in the accompanying drawings, in which:

Figure 1 is a vertical sectional view through the boiler on line 1, 1 of Fig. 4, looking in the direction of the arrow. Fig. 2 is a cross sectional view on line 22 of Fig. i looking in the direction of the arrow. Fig. 3 is a cross sectional view through the furnace showing in top plan view the boilers, and Fig. 4 is a transverse sectional view.

Reference now being had to the details of the drawings by numerals, 1 and 2 designate boilers which are mounted within the masonry wall 3 of the furnace and which wall is provided with a fuel opening 3*.

4 designates a bridge wall, to the rear face of which is fastened an atomizing chamber 5 having an aperture in the wall thereof in which the tapering end of the injector 6 is mounted and the outer end of the injector having an aperture 7 adjacent to which is disposed the tapering end of the pipe 8 and which pipe leads through the wall of the furnace.

Specification of Letters Patent.

A pipe 9 leads from the steam Patented Dec. 28, 1915.

Serial No. 10,999.

dome 10 of one boiler and through which steam is admitted to the injector for atomizing purposes. A transverse flue 11 passes from the chamber underneath the boiler l to the space underneath the boiler 2, and 12 is a horizontal partition'about the boilers dividing the space above and below the transverse centers of the boilers forming compartments 13 below the partition and provided for the purpose of causing the products of combustion to pass through the fines of the boiler in the manner indicated by the arrows. A flue 15, shown in Figs. 1 and 3 of the drawings, leads from the rear end of the boiler 1 and into which the products of combustion make exit after passing through the two boilers.

In operation, the products of combustion take the course from the fire box indicated by arrows. Live steam being introduced through the injector introduces air which commingles with the products of combustion, thus intensifying the heat. The heat is carried to the draft through the flue 11 from underneath the first boiler to the space underneath the second boiler, traveling underneath the latter to its forward end, thence back through the flues of the boiler 2 and into the flue 16, thence through the boiler 1 to the chimney, thus utilizing the maximum amount of heat units from a single furnace to heat water in the two boilers.

What I claim to be new is An apparatus for heating boilers comprising a plurality of boilers and furnace walls within which the same are mounted, said walls having a vertical partition dividing the furnace into chambers with a flue communicating between the same, a bridge wall within one of the chambers, a boxing secured to the face of said wall and having a perforated top with an aperture in the upright side thereof, an ejector having a tapering end engaging said aperture, a pipe with a tapering end positioned adjacent to the ejector member and in alinement with an opening in the outer end thereof.

In testimony whereof I hereunto affix my signature in presence of two witnesses.

CHARLES H. MCCORMICK.
